ADP1655-EVALZ

ADP1655-EVALZ is an evaluation board designed for LED drivers. This board is constructed using the ADP1655 high-efficiency, high-power LED lighting IC. It is designed to offer easy evaluation of the ADP1655 device and generates up to 600mA of continuous LED current at input voltage range of 4.75V to 30V. This evaluation board is highly efficient and allows safe and easy evaluation of the device in the lab and in the field.

The ADP1655-EVALZ’s application field includes a variety of automotive and general lighting as well as horticultural lighting. In automotive lighting applications, the board can be used for direct lighting, emergency warning lighting, interior lighting and projector lamps. In general lighting, the board can be used for power-limited lighting, linear lighting, high-power lighting and emergency lighting. In horticultural lighting, the board can be used to power LED drivers and fixtures used in indoor and outdoor gardening.

The evaluation board is constructed using a 4-channel voltage-mode architecture and is offered in power-limited, non-power-restricted versions. The non-power-limited version allows higher efficiency and better thermal management. It also offers a wide range of power delivery modes and adjustable output current. The voltage mode architecture ensures that the buck converter works on a fairly narrow range of output currents and a wide range of input voltages.

The working principle of the ADP1655-EVALZ is based on a 4-phase architecture that reduces switching losses and offers excellent current delivery. The board has four integrated controller channels, each with its own adjustable output current for buck mode conversion. The board also features a highly efficient buck mode driver with four independently adjustable voltage levels for LED current delivery. The board’s integrated PWM provides precise dimming control and is capable of dimming from 0% to 95%.

The ADP1655-EVALZ evaluates the ADP1655 device with ease and provides accurate results. The board has excellent thermal management and offers maximum safety due to a built-in current limiting feature. With its wide range of applications and its precise dimming control, the ADP1655-EVALZ board is an ideal evaluation board for LED drivers.
